Its further technological scheme is:
Said pressure cylinder can adopt the flange arrangement of global formation cylindrical shell;
The outer peripheral surface of said shell ring is provided with two circle stiffening plates.
The beneficial effect of the utility model is following:
(1) the utility model is through being connected of shell ring and abutted flange, and an end is fastenedly connected through blasting bolt, and the other end passes through tension spring and is connected with bearing pin, has effectively guaranteed Security and reliability that this device uses under abyssal environment; Improved the reliability of freeing through being provided with of single-point blasting bolt on the one hand; Through the opening/closing mechanism of tension spring, realize opening automatically of kickoff mechanism shell ring on the other hand, thereby make pressure cylinder realize freeing function.Therefore the utility model possesses stronger moulding process property, operability and safety reliability.
(2) pressure cylinder of the utility model can connect through a pair of flange butt joint; Also can use the flange arrangement of pressure cylinder global formation; Can take different processing according to different demands and Environmental Conditions, can realize processing moduleization, improve the application area of product.
(3) between a pair of flange of pressure cylinder, respectively through the seal ring sealing,, strengthened airtight performance between shell ring and the flange, can be applicable to ocean environment through the two seals design.
(4) the utility model has taked that single-point is locked frees, and needing in the existing technology to have avoided the locked complex appts of freeing of multiple spot, has reduced cost, improves accuracy and the reliability of freeing function, reduces locked and risk that fail to free.

Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described.
As depicted in figs. 1 and 2; The described deep-sea of the utility model is withstand voltage, and the round mouth flange docks locked kickoff mechanism; Comprise pressure cylinder 1; Pressure cylinder 1 forms through flange 1-1 and flange 1-2 welding butt joint, and seals through seal ring 3 respectively at the interface place at its two ends, and two ends of its butt joint back pressure cylinder 1 become protruding round mouth end; Pressure cylinder 1 outer peripheral surface place is equipped with shell ring 5, and the outer peripheral surface of shell ring 5 is provided with two circle stiffening ribs 4, increases the intensity of shell ring 5, improves reliability; Shell ring 5 is divided into first shell ring 5-1 and second shell ring 5-2, and first shell ring 5-1 constitutes the indent circular groove with its two ends, second shell ring 5-2 butt joint installation back, and the indent circular groove cooperates butt with the protruding round mouth in pressure cylinder 1 two ends, and seals through seal ring 2; See Fig. 3 and Fig. 4; Shell ring 5 connects back one of which end and is fastenedly connected through blasting bolt 6 is installed in bolt hole 11; The opposing side that its other end is positioned at the indent circular groove also is provided with larger-size groove 10; The two side of groove 10 has through hole 9, and tension spring 8 is installed in the groove 10, and first shell ring 5-1 is connected fixing with second shell ring 5-2 through bearing pin 7.
